• Write-Host returns the correct value of the data store while Export-CSV does not work

  Hi team

  I use the attached script to get vcenter inventory. Everything works fine but the output to one gives CSV value like datasore ' VMware.Vim.VirtaulMachineConfigInfoDatastroreUrlPair [of] "instead of the actual data store name.

  But when I do a write-host in the end (instead of export to CSV) I can't find the name of data reflecting properly store.

  Can someone help me understand what Miss me?

  Thanks in advance.

  The problem is that the virtual machine can have several data warehouses and the DatastoreUrl is an object, not a string.

  Try changing:

  $Report.DatastoreName = $VMview.Config.DatastoreUrl

  in:

  $Report.DatastoreName = [string]: join ('',($VMview.Config.DatastoreUrl |) Select-Object name - Expandproperty))

• root properties in the connected data store: error when accessing the date/time storage

  When you browse the properties my connected data store I get an error message when you try to read the value of the property of 'storage date/time': object doesn't support this property or method.

  Here is a minimal example:

  Dim oMyDataStore, MyProperty, oMyProperties
  
  Set oMyDataStore = Navigator.ConnectDataStoreByParameter ("TOC", "" & "C:\Program Files (x 86) \National 2012\Examples\Data\Example_data.tdm" & "" ')
  
  Set oMyProperties = oMyDataStore.RootElements (1). Properties
  
  For each MyProperty in oMyProperties
  
    Call MsgBoxDisp ("property name:" & MyProperty.Name & + "\n"&"property value:" & MyProperty.Value "")
  
  Next

  Why can I not access this particular property by default?

  Hi Phex,

  for the date/time properties, an object called UsiTimeDisp is returned. This object allows to that extend features of service as access to each part separately (day, year, hour, seconds,...) of your date/time value. If you want to print the value of time with MessageBoxDisp, you can use the VariantDate this object property.

  Your code might look like this then:

  Dim oMyDataStore, MyProperty, oMyProperties
  
  Set oMyDataStore = Navigator.ConnectDataStoreByParameter ("TOC", "" & "C:\Program Files (x 86) \National 2012\Examples\Data\Example_data.tdm" & "" ')
  
  Set oMyProperties = oMyDataStore.RootElements (1). Properties
  
  For each MyProperty in oMyProperties
  
    MyProperty.DataType = eTime Then
  
      Call MsgBoxDisp ("property name:" & MyProperty.Name & + "\n"&"property value:" & MyProperty.Value. ' ") VariantDate)
  
    On the other
  
      Call MsgBoxDisp ("property name:" & MyProperty.Name & + "\n"&"property value:" & MyProperty.Value "")
  
    End If
  
  Next

  I hope this helps.

  Good day

• Getting property of type 'Date' from a PDO data store

  It is therefore a question of both parties.  Part A: when I search for data in a data store, to find data by using the object Navigator returns the correct number of results, using the object. GetElementList does not work.  I'm looking in the data store for steps created between a certain date (using the iStartTime property).  It seems that they must return the same results.  Please see part A of my code pasted below.  Any suggestions?  Perhaps it is - that it is related to part B of my question.

  Part b: iStartTime property is the data type 30, or of type Date.  When I try to access the value of the property of iStartTime I got an error stating that ' the object does not support this property or method ".  Is there a special way to get the value of a property when the property is a date?

  Any suggestion would be appreciated!

  Sorry, I've replaced iStartTime by measurement_begin to make it work on my local database :-)

  The point is that the syntax of GetElementList is the following

  "iStartTime > = 20121201033; iStartTime<>

  When converting a CDate to str it cause string locale-dependent.

  But the suggestion would be to use the

  Dim query: query = oMyDataStore.CreateQuery set

  instead of the query string. Because he avoid conversion errors. Be aware that even a double value to a string in Germany for example will convert a written decimal number while the stringquery expects at this point notation.

  Set MyElementList = oMyDataStore.GetElementList ("Action", "measurement_begin > =" & RTT (StartDate, "#YYYYMMDDhhnnss") & ") measurement_begin<=" &="">

  must provide correct results.

• Search by wildcard characters in the data store

  I'm trying to search with a wildcard in a PDO data store.

  This produces a result:

  Back EMF Date: time 2012-08-20: 14:16:04

  But that does not

  Return *.

  How can I use wildcards in a search for data store?

  I guess that all of the following conditions must create correct results

  Dim query: query set = store. CreateQuery
  
  query. ReturnType = "measure".
  
  query. Conditions.Add 'Measure', 'name', 'is', ' back. "
  
  store. Search (Query)

  store. GetElementList ("Action", "name = % rear", true)

  store. GetElementList ("Action", "name = back *", false)

  store. GetElementList ("Action", "name = back *")

  Please take into account the fact that the PDO does not support case-insensitive query.

  I assume you are using an AVL Puma. You may need to set a switch in advanced the PDO connection dialog box. 'Use as instead of GAME'.

  If anyone knows what I m hurt you showme how please!

  Two thoughts:

  1. If you have changed somehow the object type that you want to keep, you must remove the Simulator files before running again.
  2. How about you provide a clue as to where the class cast exception that happens? You are more likely to help in this way.

• ODI file data store

  Hi all

  I have a confusion about the physical and logical length in the ODI file data store.

  I have a fixed-width file where a c2 col had datatype as string (30).

  I've set this column in the data as string store > physical length 30 > logic length 30

  My interface failed with error as '.

  ORA-12899: value too large for column 'S0_IDM '. «C$ _0S0_EAGLE_DWHCDC_CHRG_MST ".» "" "C2_CHARGE_DESC" (real: 31, maximum: 30).

  When I increased the logical length to 255, the interface worked fine.

  Being always the same 30 physical length.

  How different is it?

  Any help on this will be appreciated.

  Thanks and greetings

  Reshma

  This isn't the official documentation, but here's my point of view, after a few moments of reflection

  Everything you do in the ODI Designer is inspired by the logical architecture. Only when running it manifested in a physical implementation i.e. connection strings are materialized etc. When you perform an integration ODI creates usually a few temporary tables prefixed with C$, I$ etc to be able to perform the necessary data movement and the transformations needed to, for example, to fill a data target (table) store. In your example, your flat file is materialized in such a temporary table before that its content is manipulated (or not) and loaded in the target data store. When ODI generates this code that he uses the logical length emitted in the DDL that generates temporary table column lengths, the physical column is ignored.

  Now in your scenario is not a problem as constraints such as these do not matter to the physical file version knowledge if you were to write to the file, that it would not matter if you wrote return 255 characters or 31. This could be a problem if you were using database tables and varying the logical vs physical lengths but generally you reverse engineer tables from database using ODI rather than manually doing so makes better.

  Anyway, in short, I think that the logical lengths should be taken as representative which will manifest itself in the materialization of the temporary objects used to manged / transform the data from the source models (tables$ CAN) and target (I have tables$) while the physical lengths indicate what the underlying physical representation of these models are in reality.

  EDIT: after reading some logical documentation actually represents the length while physics is related the number of bytes required to store the data. Therefore, you could have a situation with multibyte characters where the physical length could be greater than the logical length but not really the other way around.

• get support scsi LUNS for the data store?

  I've been delving into the different classes available to HostSystem.queryHostConnectionInfo () and none of the properties appear to contain the id of naa I see when I look at LUNS on an HBA.  How do you get to LUN support for a data store?

  Figured it out.  For anyone else who wants to know:

  I created two actions, one to return a hash of the id of naa-online data store object and another action to return a hash of the naa-online drive scsi id

  // actions

• Disk groups are not visible cluster. vSAN datastore exists. 2 guests (on 8) cluster do not see the vSAN data store. Their storage is not recognized.

  http://i.imgur.com/pqAXtFl.PNG

  Do not know how even tear it down and rebuild it if the disk groups are not visible. The discs are in good health on each host storage adapters.

  Currently the latest version of vCenter 5.5. Hosts running 5.5 build 2068190

  Just built. Happy to demolish and rebuild. Just do not know why it is not visible on the two hosts and the disk groups are only recognized 3 guests when more are contributing. Also strange that I can't get the disk groups to fill in vCenter. I tried two different browsers (chrome and IE).

  I have now works.

  All the identical 5.5 relies on ESXi hosts. All hosts are homogeneous CPU/sum of the prospects for disk controller / installed RAM/storage.

  I have work. I had to manually destroy all traces of the vSAN on each single to help host node:

  (1) put the hosts in maintenance mode and remove the cluster. I was unable to disable vSAN in the cluster, I made on each node host (manually via the CLI below) then disconnected web client vCenter and return to finally refresh the ability to disable on the cluster.

  esxcli vsan cluster get - to check the status of each host.

  esxcli vsan cluster drop - the vSAN cluster host.

  storage of vsan esxcli list - view records in the individual host group

  esxcli vsan storage remove-d naa.id_of_magnetic_disks_here - to remove each of the disks in the disk group (you can ignore this using the following command to remove the SSD only falling each disc in this host group).

  esxcli vsan storage remove s naa.id_of_solid_state_disks_here - this is the SSD and all the magnetic disks in a given disk group.

  After that, I was able to manually add hosts to the cluster, leave maintenance mode and configure the disk groups. Aggregated data of the vSAN data store is correct now, and everything is functional.

  Another question for those of you who still read... How to configure such as the VM storage strategy that migrates towards (or inspired) the vSAN data store will immediately resume the default storage policy, I built for VSANs?

  Thanks for anyone who has followed.

• VM shows this in the NFS data store after passed to the vmfs data store

  Hello

  (1) create a virtual machine using NFS datastore

  (2) had created a few snapshots

  (3) to migrate this virtual machine from the data to the local VMfs store

  (4) all the files are moved to the defined vmfs datastore

  (5) storage > > nfs_datastore > > objects > > VM > > vm is present

  (6) but when did change the setting of this VM, vm is present on the data store local vmfs

  The .vmsn file contains binary data text, so you better not change it manually. The purpose of these files is to be able to return to his instant partner. Depending on the configuration of virtual machines in time you created the snapshot, the virtual machine may require access to the old data store to access the files and folders in there when you return to this snapshot.

• Move the location of the VM swap file in another data store

  Hi all

  Was in a task to move the 1000 to the file location of VM swap on another data store which is newly assigned to Exchange us to the existing store database file that will be decommissioned.

  Eager to check if anyone has made movement swap of VM location of the files to a data store to another and that all measures taken to move.

  Require some VM downtime?

  Thanks in advance a ton.

  Yes it is possible without interruption of service to virtual machines.

  1. make sure that your cluster is configured to use swap data store specified by host

  2. take a host in the cluster in maintenance mode, change the location of the VM configuration file to point to the new data store

  3. do this for all hosts in the cluster

  When you vMotion a VM from one host to another the swap file will get moved to the new data store. Later when you take guests to the maintenance and return output mode, vMotion occurs for each computer in the cluster virtual and file is moved.

• Try to re-signing and mount a data store

  Hi all

  I'm stuck trying to develop a "workflow" and hoping you can help. We need to make a daily DR copy of a production database and edit this copy on another virtual machine. The database feeds a hard with his own logic unit number and is heavily used, so we can suspend only wrote a few minutes.

  
  

  Here are the high-level workflow:

  1. Suspend the entries in the database
  2. Create a virtual copy (snapshot) of the LUN on our 3PAR
  3. Resume database entries
  4. Export (present) the virtual copy of the 3PAR to the ESXi cluster
  5. A rescan storage on all hosts in the cluster
  6. Add the LUN and re-signature of the data store
  7. Mount the VMDK from the new LUN to the VM test

  I fight a bit to make the portion of ESXi work. I can re-scan storage successfully on my host, but I'm not able to go up and re-signing of the data store newly discovered. Onyx told me to use resignatureUnresolvedVmfsVolume_Task , but the action failed with "TypeError: cannot find the resignatureUnresolvedVmfsVolume_Task function in the object (Instance) DynamicWrapper: [VcHostSystem]-[class com.vmware.vmo.plugin.vi4.model.VimHostSystem]" I run 5.5.2 vRO/vCO and don't have the library installed vi4 nor do I have all the actions that will be re-signing a volume.

  So I wonder, ResignatureUnresolvedVmfsVolume_Task has been deprecated and replaced by something else? Or did someone knows a library/plugin that I can add to vRO who will give me the opportunity to re-signing a data store?

  Thanks in advance for any help.

  See you soon!

  Hello

  The error message, it seems you are trying to call the method resignatureUnresolvedVmfsVolume_Task() on the object of type VcHostSystem. something like that

  var task = hostSystem.resignatureUnresolvedVmfsVolume_Task(spec);
  

  The problem is that resignatureUnresolvedVmfsVolume_Task() is not a method of type VcHostSystem, but in VcHostDatastoreSystemcharacters, therefore, you get this error.

  To fix it, you must obtain an object of type VcHostDatastoreSystem. Research in the API Explorer, you should be able to get VcHostDatastoreSystem object VcHostSystem object through the configManager property (which returns an object of type VcHostConfigManager), then property of datastoreSystem . Something like the following code:

  var task = hostSystem.configManager.datastoreSystem.resignatureUnresolvedVmfsVolume_Task(spec);
  

  I don't have a good environment to test, but it should work.

  I hope this helps.

• Removal of LUNS in a data store

  I installed a new volume of virtual disk of three 2 TB (RAID5) SAS drives on our HP SAN. So I have 4TB as the disk capacity that LUN. Now I was ignorant of the fact that the maximum size of a data store for ESXi 4.1 2 TB - 512 bytes. So when I added this new 4 TB LUN to a store of data on ESXi 4.1.0, only 1.64 TB has been appearing as available as against 4 TB or 3.64 to capacity. Now, I want to delete this new LUN of this data store and return to the utility of HP storage to recreate smaller i.e. two 2 TB LUN management. However, the problem I have is, I don't know how to remove this new LUN in the data store to which I added this without losing data or a data store. In my case, I had a data store 300 GB to 1.09 and I added this new 1.64 TB LUN to this Datastore.But I want to delete this LUN data store. Thank you, Clément

  I'm afraid there is no way taken in charge to remove a measure from a data store. If you want to use the entire disk space, you must destroy the entire data store.

• Data store to the way policy script host

  Hi all

  I use this little script to identify the host LUN political path and status, but hoped someone could help to change the LUN list with a naa starting with naa.600500* and rather than list the lunName data store name?

  $lunpathinfo = @()
  foreach ($vmhost in get-cluster "CLUSTER" | get-vmhost) {
  $hostview= to seen $vmhost. id
  $hostview. config . StorageDevice . multipathinfo . lun | % { `
  $lunname = $_.id
  $lunpolicy = $_.policy.policy
  $_.path | % {
  $pathstate = $_.pathstate
  $lunpathinfo += ' | Select @{name = "Hostname"; expression = {$vmhost.name}}.
  @{name = "LunName"; expression = {$lunname}},
  @{name = "LunPolicy"; expression = {$lunpolicy}},
  @{name = "PathState"; expression = {$pathstate}}
  }
  }
  }
  $lunpathinfo | Export-csv c:host_luns.csv

  Hello, nicholas1982-

  You can also retrieve the CanonicalName of LUN, so as to then be able filter on them.  You can do filtering in the script foreach block, or, probably a more reusable way, return the CanonicalName as property and then filter on this subject.  So, as:

  &{foreach ($vmhost in Get-Cluster "CLUSTER" | Get-VMHost) {    ## the .Net View of this host, with just a select set of properties    $hostview = Get-View $vmhost.id -Property Config.Storagedevice.Multipathinfo.Lun,Config.Storagedevice.ScsiLun    $hostview.Config.Storagedevice.Multipathinfo.Lun | % {        ## the Lun "key" of this HostMultipathInfoLogicalUnit, to be used to get the corresponding ScsiLun of the same Key, so as to get the CanonicalName of the LUN        $strThisMPInfoLun_LunKey = $_.Lun        $lunname=$_.Id        $lunpolicy=$_.Policy.Policy        $_.path | % {            New-Object -Type PSObject -Property @{                Hostname = $vmhost.Name                LunName = $lunname                LunPolicy = $lunpolicy                PathState = $_.Pathstate                ## the CanonicalName of the ScsiLun that corresponds to this HostMultipathInfoLogicalUnit                LunCanonicalName = ($hostview.Config.Storagedevice.ScsiLun | ?{$_.Key -eq $strThisMPInfoLun_LunKey}).CanonicalName            } ## end new-object        }    }}} | ?{$_.LunCanonicalName -like "naa.600500*"} | Export-Csv -NoTypeInformation -UseCulture  c:\Temp\host_luns.csv
  

  As well as the new property, I changed things a bit:

  1. past the exit the ScriptBlock objects, for more later use/handling/filtering/etc.
  2. update the call to Get-View to retrieve only the specified properties (the properties actually used and necessary), for the love of speed

  How to make this good for you?
